Abstract

We present a new family of ionic liquids (ILs) with a common cation, 1-butyl-3-methyl imidazolium, the popular [BMIM] + (also written C 4 C 1 Im + ) and a variety of anionic complexes (also called adducts) based in thiocyanate (SCN) : one blank compound, BMIM(SCN), and ten doped with metals having different oxidation states: Al +3 , Mn +2 , Fe +3 , Cr +3 , Ni +2 , Hg +2 , Zn +2 , Co +2 , Cd +2 and Cu + , forming, respectively, [BMIM] 3 [Al(SCN) 6 ], [BMIM] 4 Mn(SCN) 6 , [BMIM] 3 Fe(SCN) 6 , [BMIM] 3 Cr(SCN) 6 , [BMIM] 4 Ni(SCN) 6 , [BMIM] 2 Hg(SCN) 4 , [BMIM] 2 Zn(SCN) 4 , [BMIM] 2 Co(SCN) 4 , [BMIM] 2 Cd(SCN) 4 and [BMIM] 3 Cu(SCN) 4 . All of them were synthesized by us, except the blank IL and the Co thiocyanate, which are commercial. Obtained products have been characterized by NMR, and also by electrospray ionization, MS-ES, which allows the determination of the new ILs purities. Then, compounds have been analyzed using FT-IR and Raman spectroscopy. In addition, magnetic susceptibility and refractive index measurements were performed in some of the compounds studied, as well as thermal characterization using DSC and TGA. Finally, experimental measurements of density on all those ILs have been performed, and for some of the samples in a broad temperature range (about 100 K). In spite of being very similar compounds from the chemical point of view, they present quite different physical properties, including optical, thermal and magnetic ones… Also, they show different oxidation states (one with +1, six with +2 and other three with +3). We guess that this family of ILs will have interesting applications, mainly for photonic devices.
